Homework SoursePlease solve this in Eclipse C code cin cout etc 1 Add a man
Please solve this in Eclipse C++ code. (cin, cout, etc.)
1. Add a manual selection that interfaces with the user to your program. Add a user selection menu at the beginning of your program. You can use either switch or if else if statement todo so.
2. The user interface:
Enter your name: Tom Waits (example)
Hello Tom Waits, please select the service:
A: Investment projection B: Retirement planning C: Mortgage D: College fund E: Exit
If user select A or a, execute your lab 3 program.
If the user select B,b D or d, output “ service coming soon.”
If the user select E or e, output “Thank you.” If the user select anything else, output “Invalid selection.”
3. Check to make sure that the user is input ONLY ABCDE or abcde, when invalid selection ismade, bring the user back to selection.
4. When the user finish transaction, prompt the user for another transaction, if the user enter N,end with “Have a nice day.”
5. Under (C), load a text file called “load.txt” which has the following info
Principle:
Interest rate: (make sure you divide this number by 100)
Loan term: (in years)
Calculated and output the following information to a file called out.txt:
Hello Tom Waits:
Principle: 33.00(etc)
Interest rate: 33.00
Loan term: 5.00
Monthly mortgage is: 22.00---------------------------------------------------------
Would you like to go back to Menu?
(Y/N)(both Y or y, N or n are accepted.)
6. Under C, design a function called mort(): After taking the inputs, call the function mort() toprocess the calculations.
7. Go to the following linked for math calculation, and design your program based on theseinformation. Make sure you understand the information before you proceed. I am using Eclipse C++
